A CORPOEILION or CONNECTICUT.

Be it known that I, RICHARD LESTER WIL- oox' a citizen of the United States, residing at Waterbury, Haven and 'Stateof Connecticut, have in:

ve'nted certain new and. useful Tmprovei ments in Headers, of which the following is aspecification, reference being" had therein to the accompanying drawings.

"'ence tothe pisms' thereof.

- My invention relates to "a new and improved,header, and has particular referpunch shifting and feed mecha- The punch shifting-mechanism as dis closedherein is applicable" ,to a type of header requiring a plurality of blows to produce the desired results, while the feed,

mechanism is adapted toany header and any form of mechanism requiring a reliable feed.

It is the object of this invention, among otherthings, to produce a header with a friction feed that may be operated without the use of a'pawl, as iscommoiiin mechanisms of this character, and wherein the punch shifting mechanism and feed devices are operated from a single cam, that are adjustable both as to the extent of movement the proper time,

of the punch slide and the length of feed by elements located upon the outside of the machine, where they are readilyaccessible and easily manipulated, to provide simple and positive mechanism for stopping the feed, as

well as means for controlling the ;;same so that it will be impossible to feed except at and means for assuring always'a full length feed.

' To these, and other ends, my invention consists in the header, having .certain details of construction and combinations of parts as willhe hereinafter described and more particularly pointed out in the claims.

Referring to the'drawings, in which like numerals of, reference designate like parts in the several figures, Figure 1 is a sideele vation of my improved header; Fig.2 is a shifter arm thereon; Fig. tis a sectional 'fra-gmeiitary longitudinal section thereof,

through the gate and, crank, showing a side elevation of the punch slide and the punch block with the punchestherein; Fig. 3 is anaenlar ed front view of the punch slide, block an punches, with'the rock shaft and {View f 1 shi arm, taken uponline Specification of Letters Patent.

Fig. 9 is an enlarged sectional view of the parts, taken upon line.G H of Fig. 7" and Fig. 19 is a detail View of the link block ad ust1ng mechanism.

In the mechanism herein described, I so combine the several parts that both the shlftmgof the punch slide and the feedingv of the wire is derived from the operation of a single cam. This is a new feature in headers, and as a result thereof the number of parts is very materially reduced, with all the advantages that result therefrom, both as to economy of construction and maintenance,

as well as simplicity of operation. Adjustments are provided so that the length of the stroke of'the punch slide and the length of the feed may be varied as desired.

The feed mechanism is constructed with out the use of a pawl and ratchet; friction "devices being substituted therefor, and ele-' ments movable in the path of said friction. devices are provided to release their grip and stop the feed. This latter feature is controlled from a handle that is mounted upon a fixed part, its position thereby being always substantially the same and materially enhancing the convenience of its operation as distinguished "from the typ e'of pawl ,mechanisms above referred to, wherein the justment, either one or both of which may be dispensed with ifdesired.

54, within which-is rotatably mounted the shaft-s55 and 56, each of which is provided with a feed roll 57 and intermeshing gears 58 and 59. In one face of the gear 59 is a ring 60 and concentric therewith is a clutch plate 61 secured thereto by screws 62, and having a'plurality of notches 63 in the edge thereof,'said, notches; having roll faces 64 and end faces 65. Within each of said notches is a roll 66 that. is moved in one direction between the face 64 and the inner face of the ring 60 by a pin 67 having a head 68 thereon with an angular face which contacts with the roll 66. 5 pressing against the end of the pint? provides a yielding pressure against the roll 66. Rotatably mounted upon the roll shaft 56 is a trip head 70 having the odsetarm 71 integral therewith, within which is mounted .the block72 that is'adjustable through a screw 73 threaded therein and rotatabler "within the tri headl70 with a spiral gear 74 thereon which. meshes into aspiral gear 75 fixed upon'a shaft 76 rotatable in the trip.

head 70 through a kn b 77 fixed upon the outer end thereof. The position of the knob 77 is so relatively close to the center of 'the shaft 56 that its circular movement is very limited and it may be readily rotated K during the movement of the trip head 70 to I, vary the radial position of the block 72'- within the arm 71. A link 78 that connects the shifter arm 17 and block 72 issecured to the latter by a pin 79 and to the formerby 35, a pin 80, which is held against accidental disengagementby a catch plate 81 rotatably secured to. the link by a screvt 82 and which enters agroove 83 in. the pin 80. N The length of stroke of the link 78 is varied at point of connection thereof with the shifter arm 17, this being accomplished-bypassing the 80 through any oneofa plurality of 'holes84 ifnthe said shifter arm. This ad-' iustment is generally known as a coarse ad- 1 justment. The fine adjustment \of the feed is determined by the radial position of the block 72 within the otfsetarm 71, which, as

' above described, is secured by rotation of the'knfob 77. 1 g

so As the shifter plate 17 moves to the left,

as shown in Fig. 1, the trip head 70 is moved in the direction shown by the arrow in Fig. 7, at which time the clutch 61 (which is fastened to the trip head 70) moves the rolls 66 against the'faces 64, asisted by the I 7' action of the pins 67 andsprings 69 so that the rolls impinge between the inner surface .of the ring 60, causing a frictiol engagement between allof the parts. e ring eo will now rotate, and through it, the gear- 59,"with which itisconnected, which rotationin turn is transmitted to the shafts 56 and 55. to the rolls 57, capsing the same to impart an endwise feed movet5 went to the wire therebetw. Upon the A spring 69- by shifting the gear 58,

reverse movement of the shifter arm 17, the (trip head is moved in the opposite direction, and the clutch 61,

having faces 64, contacts with the periphery of each of the. \rolls 66 and moves them against the heads 68, and the tension of the spring 69. The;

between the clutch 61 and the ring 60' takes place, "andall of the parts move with the motion of the trip head 70. With the ar rangement of operation, outlined there is practically no additional strain. upon the shifterarm 17 from the feed while it is moving to the right in Fig. 1,,at which time the work required of the cam 15 through the action of the slide 10 is the greatest, and the-feverse is also true, that mechanism J when the shifter arm 17 is moving to the left the strain thereon and upon said cam is'greatest from the feed.-. Therefore, the

work upon the cam and shifter arm is,uniformly distributed and the mechanism and feed mechanism operate in perfect harmony, that is,when the strain thereon, by reason of the operation of'the punch mechanism, is the greatest, it is the punch shifting least from the feed mechanism, and vice versa. I a p The mechanism for stopping the feed operation comprisesa disk 84, which is rotatably mounted upon the trip head 70, with one face thereof against the face of the ring 60 (see Fig. 8), and inclosed within an overhanging lip 86 upon the gear 59. Fixed within this ring are a plurality of release pins 87, corresponding in number with the rolls 66, and projecting into the path of movement thereof and lying between. the

clutch face 64 and the ring 60. The center of these release pins 87 are more distant from the center of the shaft 56'than that of' the rolls 66, so that as they engage the said rolls they hate a tendency to force the same against the face 64 and away side of the ring 60. 1

Rotatably unounted-upon a stud 88 fixed in the trip head 70, is a release arm 89, that is connected with the pin 90, and having a roll 91 rotatably mounted upon one end thereof. A spring 92 connected at one end to a pin 93 in the outer end of the offset arm 71, and at the other end to the pin 90, always exerts its tension so as to rock the releasewarm 89 upon its pivot mounting and move the disk 84 u on its axis so as to force the release pins 8 into contact with the rolls 66.

JPiyotally secured to the body 1 upon the from the indisk 84 through the i with shame 9e by the 9.7. The ma.

'96 is provided with a, tail piece 9 8, and is rotatably mounted upona fixed stud 99. In

Figs. 1 and "(the roll.arm 195 is shown in rides against its'in'ner face, being held there 7 by the -spring'92. Whilethe parts are m;

these relative positipns the disk 84 moves with the trip head 70 asa'unit, and the release pins 87 and rolls 66 o ccupy the relative positions substantially as shown in Fig. 7

To move the'rolls 66-so as td prevent them having a frictional engagement with the clutch61 and ring 60,1the handle 96 is-moved upon its pivot mounting to. the "position shown by broken lines inQ-Figs." 1 and 7 which brings the roll arm 95 to the position the curved portion or sweep thereof tric to the axis of the shaft 56. i

The'sprihg 92st'illmaintains 1 1 6 ro]li.,.91 in contact'therewith but while moving to this latter pos'nl is eccen Ion, the release arn -8 9 .iS .moved upon :its pivot mounting and [an in:

idependent movement is given to the 84 through the 'pin'90 and the release pms 87 are moved against the rolls 66, which shift and) break their frictional engagement between the clutch face 64 and the ring 60. So long as the roll arm 95 occupies. the last. de-

scribed position, theshafts 56 and fre main stationary and no feed movement is transmitted. to the rolls" 57m When the handle 96 is in the position showii by full lines in .Fi .v 1, tlie'trip 1atch48is' in the position sliown by broken lines in Fig; 6, at 'whichtime it will be observed thatthe screw.

51 in'the end of said latch is out of the path of movement of the head bracket 43,. the trip arm 49 being held against the tailpiece 498' by the spring pressed pin 53. It .is there'- fore impossible to discontinue the feed operation when the parts are in this relative position; w When the handle96 is moved to the ,posi t'ron shown by dotted linesin Fig, 1,. against the stop pin 101, the-tail piece 98 has moved tosuch a position thatjt is en ged by the 50 notch 100-in thejouter'end of I pressed pin 53 w the position shown by full lines a in Fig. 6 and eifectually locks said handle 96 against further' movement until the trip latch 438 is released. This is done atthe next movementof the head 43, which engages the end of the screw 51androcks the trip latch andmoves the same out of the path of the t1 -ip"arm. 98, and"the handle I 96 can-now be again operatedso asto reestablish the feedingoperation. It will be the-operator attempting to catch a fast m ov shown by broken lines in Fig. 1,'*wherein" 't iPe -m' I 49, which is (then moved by the spring ebserved, that with this device, instead of 1 .thecase with the ratchet and pawl mechaj vnism in commonuse, it is only necessary for him to a conveniently located stationary'handle that is always in the same relative postion.
